I'm not disagreeing with you on the long term. I'm disagreeing on the 5-20 year range. If we give politicians the out of "waiting for nuclear to carry the base load" they will take it, and we will be completely fucked (or rather our children will be).

Nuclear needs investment, and will let us continue to grow, post fossil fuels. It will take time to regain the knowledge base we have already lost however, as well as building the next generation of nuclear power stations properly (as opposed to the old modified bomb factories).
